- 1.
Amatilah gambar di samping!Komponen yang ditunjukkan pada nomer komponen 4 adalah...
- A.
Accu
- B.
Kunci kontak
- C.
Distributor
- D.
Coil pengapian
- E.
Platina
Correct Answer
C. DistributorExplanation
The component shown in the picture is the distributor. The distributor is responsible for distributing high voltage from the ignition coil to the spark plugs in the correct firing order. It also regulates the timing of the spark to ensure optimal combustion in the engine.Rate this question:

Igniter pada sistem pengapian elektronik berfungsi...
- A.
Memutus dan menyambung arus listrik yang mengalir ke kumparan primer coil pengapian
- B.
Menaikkan tegangan coil pengapian
- C.
Menyerap loncatan bunga api listrik pada coil pengapian
- D.
Menyimpan arus listrik sementara
- E.
Menyimpan energi listrik
Correct Answer
A. Memutus dan menyambung arus listrik yang mengalir ke kumparan primer coil pengapianExplanation
The igniter in an electronic ignition system functions by interrupting and connecting the electric current flowing to the primary coil ignition coil. This interruption and connection of the electric current is necessary to generate the high voltage required for the ignition process. By controlling the flow of current to the primary coil, the igniter is able to create the necessary spark to ignite the fuel-air mixture in the engine.Rate this question:

Pada sistem pengapian semi elektronik untuk memajukan saat pengapian berdasarkan putaran mesin menggunakan...
- A.
Octan selektrot
- B.
Kapasitor
- C.
Centrifugal advance
- D.
Vacuum advance
- E.
Distributor
Correct Answer
C. Centrifugal advanceExplanation
Centrifugal advance is used in a semi-electronic ignition system to advance the ignition timing based on the engine's rotation. This means that as the engine speed increases, the centrifugal force causes the advance mechanism to move, which in turn advances the ignition timing. By advancing the ignition timing, the spark plug fires earlier, allowing for better combustion and improved engine performance. Therefore, centrifugal advance is an essential component in a semi-electronic ignition system to optimize the ignition timing for different engine speeds.Rate this question:

Apa fungsi no 8 yang ditunjukkan pada gambar di samping
- A.
Menyimpan arus listrik
- B.
Membagi tegangan tinggi ke masing-masing busi sesuai dengan FO
- C.
Memutus dan menyambung arus listrik
- D.
Menaikan tegangan dari 12 volt menjadi tegangan tinggi
- E.
Memutus dan menyambung arus listrik ke kumparan primer supaya terjadi tegangan induksi yang sangat tinggi di kumparan sekunder
- F.
Memutus dan menyambung arus listrik yang mengalir ke kumparan primer
Correct Answer
B. Membagi tegangan tinggi ke masing-masing busi sesuai dengan FOExplanation
The correct answer is "Membagi tegangan tinggi ke masing-masing busi sesuai dengan FO". This means that the function of number 8 in the picture is to distribute high voltage to each spark plug according to the firing order.Rate this question:

Pada sistem pengapian semi elektronik masih menggunakan sistem pengajuan konvensional yaitu:
- A.
Centrifugal advance dan vacuum advance
- B.
Manifold pressure
- C.
Intake air temperatur
- D.
Centrifugal advance dan vacuum member
- E.
Oktane selektor dan control timing
Correct Answer
A. Centrifugal advance dan vacuum advanceExplanation
The correct answer is "Centrifugal advance dan vacuum advance." In a semi-electronic ignition system, the conventional method of timing adjustment is still used, which includes centrifugal advance and vacuum advance mechanisms. These mechanisms help to adjust the ignition timing based on engine speed (centrifugal advance) and engine load (vacuum advance), ensuring optimal combustion and engine performance.Rate this question:
